Hmmmm... da1s2 is marked as 'extended' under fdisk, and it's not
apparently mounted under FreeBSD. However, the boot-up disk scan is
finding what looks sufficiently like a FreeBSD disklabel that it is
getting confused. I guess that you may at one time have had a FreeBSD
slice starting at the same place as your da1s2 slice or maybe you
typo'd one time you were using disklabel.
Can you show us the output of:
disklabel da1s2
What should the da1s2 slice contain? One way of curing the problem
would be to zero the slice contents (ie. dd if=/dev/zero of=/dev/da1s2
sort of thing) but that's no good if you've got valuable data there.
Cheers,
Matthew
